Free and open-source software (FOSS) is computer software that can be classified as both free software and open-source software. That is, anyone is freely licensed to

  • use,
  • copy,
  • study, and
  • change

the software in any way. The source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is usually hidden from the users. See Free and open-source software article on Wikipedia for more information.

FOSS for Geospatial

In 2006 was founded OSGeo Foundation to support the collaborative development of open source geospatial software, and promote its widespread use.

The foundation has adopted principles to ensure that projects under OSGeo umbrella will satisfy basic quality requirements, namely:

  • Projects should manage themselves, striving for consensus and encouraging participation from all contributors - from beginning users to advanced developers.
  • Contributors are the scarce resource and successful projects court and encourage them.
  • Projects are encouraged to adopt open standards and collaborate with other OSGeo projects.
  • Projects are responsible for reviewing and controlling their code bases to insure the integrity of the open source baselines.

This principles ensure that OSGeo projects are well established, stable, mature and sustainable.
